This originally appeared in the July 1997 Enigma, and was my first
variety cryptic; many thanks to Hot and Trazom for their editing. The
abbreviations MW, 10C, and NI3, as usual in the National Puzzlers'
League, refer to Merriam-Webster, and their 10th Collegiate and
3rd New International Dictionary.

Twelve Fifty

by Ucaoimhu

One-third of the 45 clue answers must be altered before being entered
in the grid. The required alterations, all indicated by the title, are
divided equally among three different types. Answers include five
capitalized words. Five answers are not MW, although one is 10C-inferable
and another, a foreign word, can be found in NI3.
